  • Publication number: 20190135084
    Abstract: In a heat exchange unit, a shutter device is disposed on a vehicle front side with respect to a coolant heat exchanger to open and close a passage for traveling air directed toward the coolant heat exchanger. A blower is switchable between a first blowing state in which air flows from the vehicle front side to the vehicle rear side and a second blowing state in which air flows from the vehicle rear side to the vehicle front side. In a case where a switch that makes a vehicle travelable is in an on state, a control unit switches the blower to the second blowing state, while an open degree of the shutter device is set at a closing side from a maximum open degree of the shutter device when a temperature of the engine coolant is equal to or lower than a predetermined temperature determination value.

  • Publication number: 20190033779
    Abstract: A photosensitive drum is rotatable about a first axis extending in a particular direction. A frame rotatably supports the photosensitive drum. A developing roller is rotatable according to driving force about a second axis extending in the particular direction. A surface of the developing roller contacts a surface of the photosensitive drum through toner. A resistance generating member generates a resistance torque TQ1 serving as resistance between the frame and photosensitive drum in a case where the photosensitive drum rotates relative to the frame. In a case where the developing roller rotates according to the driving force in a state where the surface of the developing roller contacts the surface of the photosensitive drum through toner, the resistance torque TQ1 is smaller than a torque TQ2 that causes the photosensitive drum to rotate due to friction between the surface of the developing roller and the surface of the photosensitive drum.

  • Publication number: 20190025124
    Abstract: A measurement auxiliary member is placed on an arrangement surface of a prism. A measurement object is placed on an upper surface of the measurement auxiliary member. The measurement auxiliary member totally reflects the terahertz wave input from a lower surface by the upper surface and outputs the totally-reflected terahertz wave from the lower surface. A main pulse of a terahertz wave totally reflected by the upper surface of the measurement auxiliary member without multiply-reflected inside any optical element on an optical path of the terahertz wave, and a noise pulse of a terahertz wave multiply-reflected inside any optical element on the optical path and reflected on an interface between the prism and the measurement auxiliary member, are temporally separated from each other when detecting a correlation by a terahertz wave detection element.

  • Publication number: 20170204780
    Abstract: In an intake air cooling device, a heat-exchanging core portion in an intercooler has an intake-air downstream-side core portion and an intake-air upstream-side core portion located upstream of the intake-air downstream-side core portion in a flow of intake air. The intake-air downstream-side core portion is located upstream of the intake-air upstream-side core portion in a flow of a cooling fluid. The intercooler has a U-turn portion at which a flow direction of the cooling fluid turns around between the intake-air downstream-side core portion and the intake-air upstream-side core portion. A flow rate control device intermittently supplies the intercooler with a predetermined volume of the cooling fluid at a time. The predetermined volume is a value determined on basis of a volumetric capacity of a cooling fluid channel in the intake-air downstream-side core portion.
